INVERSION OF LOSSY DIELECTRIC PROFILES USING PARTICLE SWARM OPTIMIZATION
2009
An electromagnetic inversion method is proposed for the reconstruction of lossy dielectric slabs. The inversion is done using particle swarm optimization hybridized with Quasi-Newton algorithm. The inversion process is applied to reconstruct dielectric slabs with discrete or continuous proflles. Accurate reconstruction of lossy dielectric slabs is obtained from inversion of re∞ection coe-cient data of normally incident plane waves in the specifled frequency range. The proposed algorithm is also tested using noisy data and showed satisfactory performance.
